Site
Recovery Manager Server
instances use several network ports to communicate with each other, with client
plug-ins, and with
vCenter Server.
If any of these ports are in use by other applications or are blocked on your
network, you must reconfigure
Site
Recovery Manager to use
different ports.

Site
Recovery Manager uses
default network ports for intrasite communication between hosts at a single
site and intersite communication between hosts at the protected and recovery
sites. You can change these defaults when you install
Site
Recovery Manager. Beyond
these standard ports, you must also meet network requirements of your
particular array-based replication provider.

You can change the network
ports from the defaults when you first install
Site
Recovery Manager. You cannot
change the network ports after you have installed
Site
Recovery Manager.
